This application is a continuation application, claiming priority under § 365(c), of an International application No. PCT/KR2021/005556, filed on May 3, 2021, which is based on and claims the benefit of a Korean patent application number 10-2020-0068614, filed on Jun. 5, 2020, in the Korean Intellectual Property Office, and of a Korean patent application number 10-2021-0005507, filed on Jan. 14, 2021, in the Korean Intellectual Property Office, the disclosure of each of which is incorporated by reference herein in its entirety.

BACKGROUND 1. Field

The disclosure relates to an electronic device having an extendable flexible display.

2. Description of Related Art

The term “electronic device” may mean a device performing a particular function according to its equipped program, such as a home appliance, an electronic scheduler, a portable multimedia player, a mobile communication terminal, a tablet personal computer (PC), a video/sound device, a desktop PC or laptop computer, a navigation for automobile, etc. For example, as electronic devices are highly integrated, and high-speed, high-volume wireless communication becomes commonplace, an electronic device, such as a mobile communication terminal, is recently being equipped with various functions. For example, an electronic device comes with the integrated functionality, including an entertainment function, such as playing video games, a multimedia function, such as replaying music/videos, a communication and security function for mobile banking, and a scheduling or e-wallet function. Such electronic devices become compact enough for users to carry in a convenient way. The electronic devices may output stored information as voices or images.

A screen display area (e.g., display) equipped in the electronic device may output content, such as text or images, providing various pieces of visual information to the user. As entertainment functions or multimedia functions of electronic devices are greatly developed, users may prefer high-definition and large-screen display areas (e.g., large-screen displays).

The electronic device typically comes equipped with a flat display device and a battery and has an outer shape, such as a bar, folder, or sliding shape. As electronic communication technology develops and electronic devices come in compact size, electronic device which may be put on the user's wrist, head, or other body portions are commercially available. Recently, electronic devices are made more compact while providing various functions as are wearable electronic devices as well as mobile communication terminals, meeting customers' needs.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

SUMMARY

Given its small size, the electronic device worn on the user's body part may have a limitation in increasing the size of the screen display area (e.g., display). For example, when the electronic device is made in reduced size, it may be difficult to install a large-screen display area, so that users receive various pieces of visual information through the display area of a small screen, rather than a large screen. Accordingly, the electronic device equipped with the display area of a small screen has difficulty in providing various pieces of information and suffer from deteriorated user convenience.

In this state, when the rotation shaft 450 a rotates, as shown in FIGS. 10 and 11A above, the first gear portion 451 disposed on the rotation shaft 450 a may be gear-rotated by the third gear portion 453 meshing with the first gear portion 451. In this case, the first gear portion 451 may rotate about the first rotational axis C1. The first and second housings 410 and 420 and the flexible display 440 may rotate about the first rotational axis C1 by the first and third gear portions 451 and 453.

According to various embodiments, a supporting member 490 facing the mounting member 460 and supporting rotation {circle around (1)} of the first and second housings 410 and 420 may be disposed on the second surface of the first housing 410. For example, the supporting member 490 may rotatably face the mounting member 460. In this state, the first and second housings 410 and 420 may be rotated about the first rotational axis C1 on the front surface of the mounting member 460 by the supporting member 490.

According to various embodiments, a through hole 491 that is through-coupled with the third gear portion 453 may be formed in the center of the supporting member 490. For example, when the supporting member 490 and the mounting member 460 face each other, the third gear portion 453 disposed on the mounting member 460 may pass through the through hole 491 and mesh with the first gear portion 451. Accordingly, the third gear portion 453 may support gear rotation of the first gear portion 451.

Referring to FIGS. 10, 11A, 11B, and 12 , the plurality of second gear portions 452 may be disposed on the rotation shaft 450 a and may include a second rotational axis C2. For example, the plurality of second gear portions 452 are meshed with the hinge gear 474 of the display supporting structure 470 and, when the rotation shaft 450 a rotates about the second rotational axis C2, may slide the hinge gear 474 of the display supporting structure 470. For example, the plurality of second gear portions 452 may include spur gears to mesh with the hinge gear 474 of the display supporting structure 470. For example, the spur gear may change rotation to linear movement. Accordingly, when the plurality of second gear portions 452 including the spur gear rotate about the second hinge axis according to the rotation of the rotation shaft 450 a, the second gear portions 452 may slide the hinge gear 474. At the same time, the display supporting structure 470 may be slid and rolled and be thus curved. In this case, the display supporting structure 470 may roll the second area 442 of the flexible display 440 while drawing out at least a portion of the second area 442 from the second housing 420. For example, when the display supporting structure 470 is slid in the sliding direction {circle around (2)} and curved, the display supporting structure 470 may slide and roll the second housing 420 in the sliding direction {circle around (2)}. In this case, the second hinge area 472 of the display supporting structure 470 may be curved and rolled, drawing out the second area 442 of the flexible display 440 from the second housing 420.

Although FIG. 12 illustrates that the internal structure of the housing 420 is exposed to the outside as the second housing 420 slides in the sliding direction {circle around (2)}, in an actual implementation, a structure to prevent the internal structure of the housing 420 from being exposed to the outside although the second housing 420 slides in the sliding direction may further be included.

Referring to FIG. 8 , one end 450 a-1 of the rotation shaft 450 a may be connected with the driving motor 480, and the other end 450 a-2 of the rotation shaft 450 a may be connected with the rotation knob 454 exposed to the outside of the first and second housings 410 and 420. For example, when the user executes at least one desired application (e.g., navigation application), the processor (e.g., the processor 120 of FIG. 1 ) provided in the electronic device 400 may operate the driving motor 480 to rotate ({circle around (1)}) the first and second housings 410 and 420 or slide the second housing 420. For example, the at least one application may include one or more applications that may perform functions such as, e.g., a home, a dialer, a short message service (SMS)/multimedia messaging service (MMS), an instant message (IM), a browser, a camera, an alarm, a contact, a voice dial, an email, a calendar, a media player, an album, or a clock, a healthcare (e.g., measuring the degree of exercise or blood sugar), or provision of environmental information (e.g., provision of air pressure, moisture, or temperature information) or navigation.

According to an embodiment, when the user executes at least one application (e.g., a navigation application), the processor 120 may apply a signal to the driving motor 480 to drive the driving motor 480. In this case, the driving motor 480 may rotate the rotation shaft 450 a about the second rotational axis C2. The rotation shaft 450 a may rotate the first gear portion 451. In this case, the first gear portion 451 may be rotated by the third gear portion 453 of the mounting member 460 to rotate ({circle around (1)}) the first and second housings 410 and 420 and the flexible display 440 about the first rotational axis C1. At the same time, the rotation shaft 450 a may also rotate the second gear portion 452 about the second rotational axis C2. For example, the second gear portion 452 may slide the hinge gear 474 of the display supporting structure 470. In this case, the second hinge area 472 of the display supporting structure 470 may be curved and rolled, sliding the second housing 420 in the sliding direction {circle around (2)}. For example, the display supporting structure 470 may be rolled to slide the second housing 420 while drawing out at least a portion of the second area 442 of the flexible display 440 from the second housing 420. For example, the first and second housings 410 and 420 and the flexible display 440 may be automatically rotated ({circle around (1)}) by the driving motor 480 and, simultaneously, the flexible display may be rolled to slide the second housing 420 in the sliding direction {circle around (2)}. In this case, at least a portion of the second area 442 of the flexible display 440 may also be exposed to the outside while being drawn out from the second housing 420. Accordingly, at least a portion of the second area 442 may be exposed to the outside. In this state, the user may be provided with various pieces of information about an application (e.g., a navigation application) selected through the first area and at least a portion of the second area of the flexible display 440.

According to various embodiments, when the user manually rotates the rotation knob 454 connected to the other end 450 a-2 of the rotation shaft 450 a with his/her hand, the rotation knob 454 may rotate the rotation shaft 450 a, and the rotation shaft 450 a may simultaneously rotate the first gear portion 451 according to the rotation. According to the rotation, the first gear portion 451 may rotate ({circle around (1)}) the first and second housings 410 and 420 and the flexible display 440. Simultaneously, the rotation shaft 450 a may rotate the plurality of second gear portions 452 according to the rotation. In this case, according to the rotation, the plurality of second gear portions 452 may roll the flexible display 440 to slide the second housing 420 in the sliding direction while manually drawing out at least a portion of the second area 442 of the flexible display 440 from the second housing 420. Accordingly, at least a portion of the second area 442 of the flexible display 440 may be exposed to the outside according to the rotation of the rotation knob 454.

Accordingly, when rotated by being driven by the driving motor 480, the rotation shaft 450 a may automatically rotate ({circle around (1)}) the first and second housings 410 and 420 and the flexible display 440 while automatically exposing at least a portion of the second area 442 to the outside.

According to various embodiments, when the user holds the rotation knob 454 with his/her hand to rotate the rotation shaft 450 a, the rotation shaft 450 a may manually rotate the first and second housings 410 and 420 and the flexible display 440 while manually exposing at least a portion of the second area 442 to the outside.

Accordingly, the first and second housings 410 and 420 and the flexible display 440 may automatically be rotated by the driving motor 480 while automatically extending the flexible display 440. Further, the first and second housings 410 and 420 and the flexible display 440 may manually rotate the first and second housings 410 and 420 and the flexible display 440 by the rotation of the rotation knob 454 while manually extending the flexible display 440.

According to various embodiments, as shown in FIGS. 5 and 7 , the third gear portion 453 fitted into the through hole 491 formed in the center of the supporting member 490 may be disposed in the center portion of the mounting member 460, and the first and second binding members 462 and 463 may be disposed around the outer circumference of the mounting member 460. For example, the first binding member 462 may include a band guide member 464 including a fixing member 465 fitted into a plurality of coupling holes 467 included in the second binding member 463 described below. For example, the first and second binding members 462 and 463 may be disposed to extend and protrude away from each other from the outer circumference of the mounting member 460. In this state, the mounting member 460 may be placed on the user's wrist, and the second binding member 463 may be inserted into the band guide member 464 of the first binding member 462. In this case, since the band guide member 464 includes the fixing member 465, the fixing member 464 may be inserted into the plurality of coupling recesses of the second binding member 463, binding and fixing the first and second binding members 462 and 463.

In this state, when the user executes a navigation application among at least one application of the electronic device 400, the processor 120 may drive the driving motor 480 in a first direction. The driving motor 480 may be driven by the processor 120 in the first direction while simultaneously rotating the rotation shaft 450 a about the second rotational axis C2. The rotation shaft 450 a may rotate the first and second gear portions 451 and 452. According to the rotation, the first gear portion 451 may rotate ({circle around (1)}) the first and second housings 410 and 420 and the flexible display 440 about the first rotational axis C1. Simultaneously, the second gear portions 452 may also be rotated to slide the hinge gear 474 of the display supporting structure 470, and the second hinge area 472 of the display supporting structure 470 may be curved and rolled to slide the second housing 420 in the sliding direction {circle around (2)}. In this case, the second hinge area 472 of the display supporting structure 470 may draw out at least a portion of the second area 442 of the flexible display 440 from the second housing 420. Accordingly, the first area 441 of the flexible display 440 and at least a portion of the second area 442 of the flexible display 440 may be exposed to the outside. In this case, the user may receive information about the navigation application through the extended flexible display 440.

Referring to FIGS. 11B and 12 , as the first area 441 and at least a portion of the second area 442 of the flexible display 440 are exposed to the outside, the flexible display 440 may secure an enlarged large-screen display area so that users may receive various pieces of visual information through the large-screen display area. Accordingly, the extended flexible display 440 may easily provide various pieces of application information to the user.

According to various embodiments, when the user does not execute the navigation application, the processor 120 may re-drive the driving motor 480. The driving motor 480 may be driven by the processor 120 in a second direction (e.g., reverse direction) opposite to the first direction (e.g., forward direction) while simultaneously rotating the rotation shaft 450 a about the second rotational axis C2. The rotation shaft 450 a may rotate the first and second gear portions 451 and 452. According to the rotation, the first gear portion 451 may rotate ({circle around (1)}) the first and second housings 410 and 420 and the flexible display 440 about the first rotational axis C1. Simultaneously, the second gear portions 452 may also be rotated. According to the rotation, the second gear portions 452 may curve and roll the display supporting structure 470, sliding it in the direction opposite to the sliding direction {circle around (2)}. For example, the display supporting structure 470 may also slide at least a portion of the second area 442 of the flexible display 440. In this case, the display supporting structure 470 may slide at least a portion of the second area 442 in the direction opposite to the sliding direction {circle around (2)} while simultaneously sliding the second housing 420 in the direction opposite to the sliding direction {circle around (2)} back to the original position. Accordingly, the display supporting structure 470 may be curved and rolled, sliding the second housing 420 in the direction opposite to the sliding direction {circle around (2)} back to the original position while simultaneously drawing at least a portion of the second area 442 of the flexible display 440 in the second housing 420.

As such, the flexible display 440 configures the display supporting structure 470 which is curved according to the rotation of the gear structure 450 to support the rolling of the flexible display 440. Thus, the display supporting structure 470 may easily extend the flexible display 440, thus easily providing a large-screen display area of the flexible display 440. Accordingly, the user may extend the flexible display 440 according to the purpose of use of the electronic device, further enhancing the user's convenience.

FIG. 13A is a perspective view illustrating a device portion 401 and a mounting portion 402 separated from each other in an electronic device 400 with a flexible display 440 according to an embodiment of the disclosure. FIG. 13B is a view illustrating a gear plate 493 for coupling with a mounting portion 402 in a device portion 401 of an electronic device 400 according to an embodiment of the disclosure. FIG. 13C is a perspective view illustrating a coupling relationship between a mounting portion 402 and a device portion 401 in an electronic device 400 according to an embodiment of the disclosure. FIG. 13D is a view illustrating a coupling structure of a mounting portion 402 in an electronic device 400 according to an embodiment of the disclosure.

The configuration of the electronic device 400 of FIGS. 13A to 13D may be at least partially similar to the configuration of the electronic device 400 of FIGS. 5 to 10, 11A, 11B, and 12 or may include another embodiment of the electronic device.

Referring to FIGS. 13A to 13D, an electronic device 400 may include a device portion 401 where a flexible display 440 is extendably disposed and a mounting portion 402 coupled with the device portion 401 and formed to be worn on the user's body (e.g., wrist).

According to various embodiments, the device portion 401 may include first and second housings 410 and 420, a plurality of guide rails (e.g., the guide rails 430 of FIGS. 5 to 7 ), a flexible display (e.g., the flexible display 440 of FIGS. 5 to 7 ), a supporting member 490, and a gear plate 493. The mounting portion 402 may include a mounting plate 461, first and second binding members (e.g., the first and second binding members 462 and 463 of FIGS. 5 to 7 ), a band guide member (e.g., the band guide member 464 of FIGS. 5 to 7 ), a fixing member (e.g., the fixing member 464 of FIGS. 5 to 7 ), and a plurality of coupling holes (e.g., the coupling holes 465 of FIGS. 5 to 7 ).

The following description focuses primarily on a configuration different from those shown in FIGS. 5 to 10, 11A, 11B, and 12 .

According to an embodiment, the supporting member 490 may be disposed on one surface (e.g., the surface facing the mounting portion 402) of the first housing 410 to face the mounting portion 402 and support rotation of the first and second housings 410 and 420. The supporting member 490 may be rotatably coupled to the mounting portion 402. According to an embodiment, the gear plate 493 may be mounted in the center of the supporting member 490, and a through hole 491 for exposure to the outside may be formed. The gear plate 493 may include a first surface 493 b facing the device portion 401 and a second surface 493 c facing the mounting portion 402, and the third gear portion 453 protruding inward of the device portion 401 may be disposed on the first surface 493 b. The third gear portion 453 of FIGS. 5 to 7 may be applied to some shape and/or function of the third gear portion 453. For example, the third gear portion 453 formed on the gear plate 493 may be disposed to mesh with the first gear portion (e.g., the first gear portion 451 of FIGS. 5 to 7 ) to support gear rotation of the first gear portion 451. A guide portion 493 a protruding toward the mounting portion 402 may be disposed on the second surface 493 c of the gear plate 493. For example, the guide portion 493 a may include a linear protrusion for slidable coupling to the mounting plate 461 of the mounting portion 402. As an example, the guide portion 493 a may have a plurality of linear protrusions formed side by side to allow the device portion 401 to be stably coupled to the mounting plate 461.

Referring to FIG. 13B, the gear plate 493 may be coupled to be rotated relative to the supporting member 490. For example, in a state in which the device portion 401 is coupled to the mounting portion 402, the gear plate 493 may be fixedly coupled to the mounting portion 402, and the supporting member 490 fixedly coupled to the device portion 401 may be rotated about the gear plate 493. As the device portion 401 is rotated relative to the mounting portion 402, the user may freely adjust the extending direction (e.g., the direction indicated by the arrow in FIG. 13B) of the flexible display.

According to various embodiments, the mounting plate 461 of the mounting portion 402 is a portion directly contacting the user's body (e.g., wrist) and may be provided in a plate shape. The mounting plate 461 may include a recess portion 461 a for slidable coupling with the guide portion 493 a of the gear plate 493, a fixing member 461 b disposed in one area of the recess portion 461 a to fix the gear plate 493, and an elastic member 461 c disposed on one end of the fixing member 461 b to provide an elastic force. A plurality of recess portion 461 a, a plurality of fixing member 461 b, and a plurality of elastic member 461 c, corresponding to the number of guide portions 493 a of the gear plate 493, may be formed.

According to an embodiment, the recess portion 461 a may have a recess shape recessed into the mounting plate 461. At least a portion of the recess portion 461 a may be provided in a shape corresponding to the guide portion 493 a, guiding the guide portion 493 a to slide while being coupled to the recess portion 461 a. The recess portion 461 a is formed such that one end of the mounting plate 461 is opened, and the guide portion 493 a may be inserted in the opened direction and then fastened. In the recess portion 461 a, an area adjacent to the opening may be sized to seat the fixing member 461 b and the elastic member 461 c.

According to an embodiment, the fixing member 461 b may be disposed at one end of the mounting plate 461 (e.g., near the opening of the recess portion 461 a) and may be positioned in a state coupled to the elastic member 461 c. The fixing member 461 b may be provided as a component including an elastic material (e.g., rubber) and, when the guide portion 493 a of the gear plate 493 is inserted into or separated from the mounting plate 461, fix it so that more than a certain designated force is required. For example, the first portion 4611 of the fixing member 461 b may be positioned to block or open the passage of the recessed portion 461 a for the guide portion 493 a to pass therethrough. The second portion 4612 extending from the first portion 4611 may be coupled with the elastic member 461 c. The elastic member 461 c may be disposed to provide an elastic force perpendicular to the direction in which the recess portion 461 a faces and be designed to require a designated force for blocking or opening the passage as it provides an elastic force to the first portion 4611.

According to an embodiment, in the fixing member 461 b, an area (e.g., an edge area of the first portion 4611) in contact with the guide portion 493 a may be formed to have a designated curvature value R. Accordingly, when the guide portion 493 a is inserted into or separated from the recess portion 461 a, it is possible to advantageously provide movement of the fixing member 461 b positioned in the passage. For example, if the guide portion 493 a provides a force in the P1 direction to one area having the curvature value R, the first portion 4611 may convert the force in the P1 direction to move in the P2 direction, thus opening the passage for the guide portion 493 a to move. As another example, one area having the curvature value R may be formed in each of the two opposite edge areas of the first portion 4611 and may contact when the guide portion 493 a is inserted into or separated from the recess portion 461 a.

According to an embodiment, an operation for coupling or releasing the device portion 401 to/from the mounting portion 402 is described. To couple the device portion 401 to the mounting portion 402, the guide portion 493 a of the gear plate 493 may be inserted into the area (e.g., the end of the recess portion 461 a) where the opening of the mounting plate 461 is disposed. The end of the guide portion 493 a may contact the portion having the curvature value R of the fixing member 461 b and, if a predetermined level of force or more is applied, the elastic member 461 c may be compressed, so that the recess portion 461 a may be opened. The guide portion 493 a of the gear plate 493 may slide along the opened recess portion 461 a. If the slide of the guide portion 493 a is completed, compression of the elastic member 461 c may be released, and the fixing member 461 b may block the movement passage of the guide portion 493 a and fix the position of the gear plate 493. According to another embodiment, when the device portion 401 is separated from the mounting portion 402, the separation may proceed in the reverse order of the insertion for coupling.

FIG. 14 is an exploded perspective view illustrating a configuration of an electronic device 500 with a flexible display 540 according to an embodiment of the disclosure.

FIG. 15 is a cross-sectional view taken along D-D′ of FIG. 14 , illustrating a flexible display 540 and a display supporting structure 570 according to an embodiment of the disclosure.

Referring to FIGS. 14 and 15 , according to other various embodiments, an electronic device 500 may include first and second housings 510 and 520, a plurality of guide rails 530, a flexible display 540, a gear structure 550, a mounting member 560, and a plurality of stopper members 501. For example, the first housing 510 may include a first surface (e.g., front surface) 511, a second surface (e.g., rear surface) 512 facing in the opposite direction of the first surface 511, and a side surface 513 surrounding the space between the first and second surfaces 511 and 512.

According to an embodiment, the first surface 511 may face a first area 541 of the flexible display 540 to be described below, and a supporting member 590 supporting rotation {circle around (1)} of the first and second housings 510 and 520, as described below, may be disposed on the second surface 512. For example, an opening 512 a may be formed in the second surface 512 to allow the supporting member 590 to be disposed thereon.

The second housing 520 may be slidably coupled to a side surface of the first housing 510 and may be detachably coupled to the side surface of the first housing 510 and may rotate {circle around (1)} together with the first housing 510. For example, the second housing 520 may rotate ({circle around (1)}) together with the first housing 510 and slide away from or closer to the side surface of the first housing 510. For example, when the second housing 520 slides away from the side surface of the first housing 510, the second housing 520 may be separated from the side surface of the first housing 510 while extending the flexible display 540. Further, when the second housing 520 slides closer to the side surface of the first housing 510, the second housing 520 may be coupled to the side surface of the first housing 510 while shrinking the flexible display 540.

The plurality of guide rails 530 may be disposed in the first housing 510, guiding the slide of the second housing 520. For example, first ends of the plurality of guide rails 530 may be slidably fitted to the plurality of sliding recesses 510 a formed on two opposite sides of the first housing 510. Second ends of the plurality of guide rails 530 may be fitted to a plurality of coupling recesses 520 a formed on two opposite sides of the second housing 520. Accordingly, the plurality of guide rails 530 may be drawn in or out from the plurality of sliding recesses 510 a to be able to slide the second housing 520.

Referring to FIG. 15 , the flexible display 540 may include a first area 541 mounted on a first surface 511 of the first housing 510 and a second area 542 extending from the first area 541. For example, the first area 541 may include a first front surface 541 a exposed to the outside and a first rear surface 541 b which is opposite to the first front surface 541 a. The second area 542 may include a second front surface 542 a having at least a portion exposed to the outside and a second rear surface 542 b which is opposite to the second front surface 542 a.

According to various embodiments, the electronic device 500 may include a display supporting structure 570 facing the first rear surface 541 b of the first area 541 and the second rear surface 542 b of the second area 542. For example, the display supporting structure 570 may support rolling of the flexible display 540 to allow at least a portion of the second area 542 to be exposed to the outside while supporting the slide of the second housing 520 according to rotation of the gear structure 550 described below.

According to an embodiment, the display supporting structure 570 may include first, second, and third hinge areas 571, 572, and 573, and the first hinge area 571 may face and be fixed to at least a portion of the first rear surface 541 b of the first area 541. The second hinge area 572 may extend from the first hinge area 571 and, as the second housing 520 slides, the second area 542 may be curved to be drawn in or out from the second housing 520. The third hinge area 573 may extend from the second hinge area 572 and include a hinge gear 574 engaged with a plurality of third gear portions 553 included in the gear structure 550. For example, when the plurality of third gear portions 553 are rotated, the plurality of third gear portions 553 may slide the hinge gear 574 according to the rotations and, in this case, the third hinge area 573 along with the hinge gear 574 may slide. For example, if the third hinge area 573 slides, the second hinge area 572 may be curved while sliding the second housing 520 in the sliding direction {circle around (2)}. In this case, the second hinge area 572 may draw out at least a portion of the second area 542 from the second housing 520. Simultaneously, at least a portion of the second area 542 may be exposed to the outside. For example, the second area 542 may be extended from the first area 541, and the first area 541 and at least a portion of the second area 542 may be exposed to the outside.

According to various embodiments, the fourth gear portion 554 fitted into the through hole 591 formed in the center of the supporting member 590 may be disposed in the center portion of the mounting member 560 including a mounting plate 561, and the first and second binding members 562 and 563 may be disposed around the outer circumference of the mounting member 560. For example, the first binding member 562 may include a band guide member 564 including a fixing member 565 fitted into a plurality of coupling holes 565 included in the second binding member 463 described below. For example, the first and second binding members 562 and 563 may be disposed to extend and protrude away from each other from the outer circumference of the mounting member 560. In this state, the mounting member 560 may be placed on the user's wrist, and the second binding member 563 may be inserted into the band guide member 564 of the first binding member 562. In this case, since the band guide member 564 includes the fixing member 565, the fixing member 565 may be inserted into the plurality of coupling recesses 567 of the second binding member 563, binding and fixing the first and second binding members 562 and 563.

When connected to the rotation shaft 550 a, the rotation knob 555 may simultaneously be rotated along with the rotation shaft 550 a by external force and be exposed to the outside.

According to various embodiments, the plurality of stopper members 501 may include first, second, and third stopper members 501 a, 501 b, and 501 c. For example, the first, second, and third stopper members 501 may be formed on the rotation shaft 550 a and, when pulling the rotation knob 555 outward of the housings 510 and 520 by external force and sliding them, be slid along with the rotation shaft 550 a while simultaneously being coupled or separated to/from the stopper protrusion 502 disposed in the first housing 510 by elastic force.

Referring to FIGS. 16A, 16B, 17, and 18 , when the user holds the rotation knob 555 exposed to the outside of the housings 510 and 520 with his/her hand and pulls it outward of the housings 510 and 520, the rotation knob 555 may be slid to the second rotational axis C2 while simultaneously sliding the rotation shaft 550 a. In this case, the first stopper member 501 a formed in the rotation shaft 550 a may also be slid. Simultaneously, the first stopper member 501 a may be coupled to the protrusion 502 a formed in the stopper protrusion 502 of the first housing 510. In this case, when the first stopper member 501 a is coupled with the protrusion 502 a of the stopper protrusion 502, the slide of the rotation shaft 550 a may be restricted. In this case, the plurality of third gear portions 553 disposed on the rotation shaft 550 a may be engaged with the hinge gear 574 of the display supporting structure 570, and the first and second gear portions 551 and 552 may be disengaged from the fourth gear portion 554.

In this state, when the rotation knob 555 is rotated about the second rotational axis C2 in the first direction (e.g., forward direction), the rotation shaft 550 a is rotated while simultaneously rotating the plurality of third gear portions 553 and, according to the rotation, the plurality of third gear portions 553 may slide the hinge gear 574 of the display supporting structure 570. Accordingly, the plurality of third gear portions 553 may roll and curve the display supporting structure 570 according to the rotation, drawing out at least a portion of the second area 542 from the second housing 520 in the direction perpendicular to the second rotational axis C2.

The plurality of third gear portions 553 and at least one of the components of the display supporting structure 570 may be identical or similar to the plurality of second gear portions 452 and at least one of the components of the display supporting structure 470 of FIGS. 13A to 13D, and no duplicate description thereof is thus given below.

In this state, when the rotation knob 555 is rotated about the second rotational axis C2 in the first direction (e.g., forward direction), the rotation shaft 550 a is rotated while simultaneously rotating the first gear portion 551. According to the rotation, the first gear portion 551 may rotate the first and second housings 510 and 520 and the first area 541 of the flexible display 540 about the first rotational axis C1.

In this case, the first area 541 of the flexible display 540 may rotate while being exposed to the outside. The second area 542 of the flexible display 540 is not exposed to the outside.

Referring to FIGS. 24 and 25 , as the first area 541 of the flexible display 540 is exposed to the outside, the first area 541 of the flexible display 540 may provide information about various applications to the user.

According to an embodiment, the user's hand holds the rotation knob 555 and rotate it about the second rotational axis C2 in the second direction (e.g., reverse direction) opposite to the first direction (e.g., forward direction). In this case, the rotation shaft 550 a may also rotate in the second direction while simultaneously rotating the first gear portion 551 and, according to the rotation, the first gear portion 551 may also rotate the first and second housings 510 and 520 and the first area 541 of the flexible display 540 back to the original position.

According to various embodiments, when the user automatically rotates the first and second housings 510 and 520 and the first area 541, the processor 120 may drive the driving motor 580 in the first direction (e.g., forward direction). The driving motor 580 may be driven by the processor 120 in the first direction (e.g., forward direction) while simultaneously rotating the rotation shaft 550 a about the second rotational axis C2. The rotation shaft 550 a may rotate the first gear portion 551 according to the rotation. In this case, the first gear portion 551 may automatically rotate the first and second housings 510 and 520 and the first area 541 about the first rotational axis C1. Further, when the driving motor 580 is driven by the processor 120 in a second direction (e.g., reverse direction) opposite to the first direction (e.g., forward direction), the driving motor 580 may rotate the rotation shaft 550 a about the second rotational axis C2 in the second direction. In this case, the rotation shaft 550 a may rotate the first gear portion 551 while simultaneously rotating in the second direction and, according to the rotation, the first gear portion 551 may rotate the first and second housings 510 and 520 and the first area 541 about the first rotational axis C1 in the second direction, back to the original position.

As such, the user may hold and rotate the rotation knob 555 with his/her hand to manually rotate the first and second housings 510 and 520 and the first area 541 about the first rotational axis C1 and may drive the driving motor 580 to automatically rotate the first and second housings 510 and 520 and the first area 541 about the first rotational axis C1.

In this case, the rotation shaft 550 a may slide together, and the third stopper member 501 c formed on the rotation shaft 550 a may also slide. Simultaneously, the protrusion 502 a of the stopper protrusion 502 may be separated from the second stopper member 501 b while separated from the first stopper member 501 a and be then coupled to the third stopper member 501 c. In this case, when the third stopper member 501 c is coupled with the protrusion 502 a of the stopper protrusion 502, the slide of the rotation shaft 550 a may be restricted. In this case, the plurality of third gear portions 553 may also be restricted from sliding while simultaneously engaged with the hinge gear 574 of the display supporting structure 570. Simultaneously, the second gear portion 552 may slide and engage with the fourth gear portion 554.

Referring to FIG. 29 , when the rotation knob 555 is rotated about the second rotational axis C2 in the first direction (e.g., forward direction), the rotation shaft 550 a is rotated while simultaneously rotating the second gear portion 552. According to the rotation, the second gear portion 552 may rotate the first and second housings 510 and 520 and the first area of the flexible display 540 about the first rotational axis C1.

Simultaneously, the plurality of third gear portions 553 may also be rotated according to the rotation of the rotation shaft 550 a. For example, the plurality of third gear portions 553 may slide the hinge gear 574 of the display supporting structure 570 according to the rotation. Accordingly, the plurality of third gear portions 553 may roll and curve the display supporting structure 570 according to the rotation, drawing out at least a portion of the second area 542 of the flexible display 540 from the second housing 520 in the direction perpendicular to the second rotational axis C2.

The plurality of third gear portions 553 and at least one of the components of the display supporting structure 570 may be identical or similar to the plurality of second gear portions 452 and at least one of the components of the display supporting structure 470 of FIGS. 13A to 13D, and no duplicate description thereof is thus given below.

Referring to FIG. 30 , as the first area 541 and at least a portion of the second area 542 of the flexible display 540 are exposed to the outside, the flexible display 540 may secure an enlarged large-screen display area so that users may receive various pieces of visual information through the large-screen display area. Accordingly, the extended flexible display 540 may easily provide various pieces of application information to the user.

According to various embodiments, when the user automatically rotates the first area 541 and at least a portion of the second area 542, the processor 120 may drive the driving motor 580 in the first direction (e.g., forward direction). The driving motor 580 may be driven by the processor 120 in the first direction while simultaneously rotating the rotation shaft 550 a about the second rotational axis C2. The rotation shaft 550 a may rotate the second gear portion 552 and the plurality of third gear portions 553 according to the rotation. In this case, according to the rotation, the second gear portion 552 may automatically rotate the first and second housings 510 and 520 and the first area 541 about the first rotational axis C1. At the same time, the rotation shaft 550 a may also rotate the plurality of third gear portions 553 about the second rotational axis C2. For example, the plurality of third gear portions 553 may slide the hinge gear 574 of the display supporting structure 570. In this case, the display supporting structure 570 may be curved and rolled, sliding the second housing 520 in the sliding direction {circle around (2)}. For example, the display supporting structure 570 may be rolled to slide the second housing 520 while drawing out at least a portion of the second area 542 of the flexible display 540 from the second housing 520. For example, the first and second housings 510 and 520 and the flexible display 540 may be automatically rotated ({circle around (1)}) by the driving motor 580 and, simultaneously, the flexible display 540 may be rolled to slide the second housing 520 in the sliding direction {circle around (2)}.

Accordingly, at least a portion of the second area 542 may be exposed to the outside. In this state, the user may be provided with various pieces of information about an application (e.g., a navigation application) selected through the first area 541 and at least a portion of the second area 542 of the flexible display 540.

According to various embodiments, when the user does not execute the application, the processor 120 may re-drive the driving motor 580. The driving motor 580 may be driven by the processor 120 in a second direction (e.g., reverse direction) opposite to the first direction (e.g., forward direction) while simultaneously rotating the rotation shaft 550 a about the second rotational axis C2. The rotation shaft 550 a may rotate the second gear portion 552 and the plurality of third gear portions 553. According to the rotation, the second gear portion 552 may rotate ({circle around (1)}) the first and second housings 510 and 520 and the flexible display 540 about the first rotational axis C1. Simultaneously, the plurality of third gear portions 553 may also be rotated. According to the rotation, the plurality of third gear portions 553 may curve and roll the display supporting structure 570, sliding it in the direction opposite to the sliding direction {circle around (2)}. For example, the display supporting structure 570 may also slide at least a portion of the second area 542 of the flexible display 540. In this case, the display supporting structure 570 may slide at least a portion of the second area 542 in the direction opposite to the sliding direction {circle around (2)} while simultaneously sliding the second housing 520 in the direction opposite to the sliding direction {circle around (2)} back to the original position. Accordingly, the display supporting structure 570 may be curved and rolled, sliding the second housing 520 in the direction opposite to the sliding direction {circle around (2)} back to the original position while simultaneously drawing at least a portion of the second area 542 of the flexible display 540 in the second housing 520.

As such, the user may hold and rotate the rotation knob 555 with his/her hand to manually rotate the first area and at least a portion of the second area or manually slide at least a portion of the second area or may drive the driving motor 580 to automatically rotate the first area and at least a portion of the second area or automatically slide at least a portion of the second area.

According to various embodiments, the main body 1100 may further include a communication module (e.g., the communication module 190 of FIG. 1 ) for performing communication with the mounting member 1200 or an external electronic device, a memory (e.g., the memory 130 of FIG. 1 ), a driving structure (e.g., the gear structure 450 of FIG. 8 or the gear structure 550 of FIG. 14 ) configured to adjust the exposed portion of the flexible display (e.g., the display module 160 of FIG. 1 or the flexible display 1120 of FIG. 31 ) and/or rotation of the housing (e.g., the housing 1110 of FIG. 31 ), and a plurality of sensors (e.g., the sensor module 176 of FIG. 1 ) for detecting the operation state of the electronic device or external environment state.

According to various embodiments, the mounting member 1200 may include a magnet 1233 disposed in at least one of the plurality of coupling portions (e.g., the plurality of coupling portions 1230 of FIG. 31 ), a coupling detection sensor 1234 (e.g., hall integrated circuit (IC)) for detecting the coupling or separation of the plurality of coupling portions, a sub processor 1240 (e.g., the processor 120 of FIG. 1 ), a sensor 1250 (e.g., a fingerprint recognition sensor or a blood vessel recognition sensor) for user authentication, a communication module 1260 (e.g., the communication module 190 of FIG. 1 ) for performing communication with the main body 1100 or an external electronic device, a battery 1270 (e.g., the battery 189 of FIG. 1 , hereinafter referred to as a second battery), and a second coil 1280 for supplying power to the first battery 1140 and the second battery 1270 of the main body 1100. According to various embodiments, the mounting member 1200 may further include a memory (e.g., the memory 130 of FIG. 1 ) and a plurality of sensors (e.g., the sensor module 176 of FIG. 1 ) for detecting the operation state of the electronic device or external environment state.

According to various embodiments, the sub processor 1240 may be operatively connected with the components of the mounting member 1200. For example, upon detecting mutual coupling of the plurality of coupling portions, the sub processor 1240 may perform user authentication. For example, if the plurality of coupling portions are coupled through the magnet 1233, the sub processor 1240 may detect the coupling of the plurality of coupling portions through the coupling detection sensor 1234.

According to various embodiments, upon detecting the mutual coupling of the plurality of coupling portions, the sub processor 1240 may perform user authentication based on the sensing value detected through the sensor 1250 for user authentication. According to various embodiments, the sub processor 1240 may perform user authentication by comparing user information stored in the memory included in the mounting member 1200 or user information received through the communication module 1260 and the sensing value detected through the sensor 1250. Various embodiments of the sensor 1250 for user authentication are described below with reference to FIGS. 34A to 34C.

According to various embodiments, the sub processor 1240 may transmit the result of user authentication to the processor 1130. For example, the sub processor 1240 may transmit the user authentication result to the processor 1130 of the main body 1100 through the communication module 1260.

According to various embodiments, the processor 1130 may control the driving structure based on the user authentication result received from the sub processor 1240. According to various embodiments, the driving structure may include at least one of a rotation shaft (e.g., the rotation shaft 450 a of FIG. 8 ), a crown (e.g., the rotation knob 454 of FIG. 5 ) connected with a side end of the rotation shaft to manually move the rotation shaft, a sensor (e.g., the sensor module 176 of FIG. 1 ) for detecting the position of the crown, or a driving motor (e.g., the driving motor 480 of FIG. 5 ) connected with the other side end of the rotation shaft to rotate the rotation shaft about the rotation shaft. According to various embodiments, the electronic device may omit the crown and, if included, the crown may be disposed outside the housing.

According to various embodiments, as shown in FIG. 8 or 16A, a plurality of first gear portions (e.g., the second gear portion 452 of FIG. 8 or the third gear portion 553 of FIG. 16A) related to adjustment of the exposed portion of the flexible display and at least one second gear portion (e.g., the first gear portion 451 of FIG. 8 or the first and second gear portions 551 and 552 of FIG. 16A) may be disposed on the rotation shaft.

According to various embodiments, as shown in FIG. 16A, when the plurality of first gear portions (e.g., the third gear portion 553 of FIG. 16A) and the plurality of second gear portions (e.g., the first and second gear portions 551 and 552 of FIG. 16A) are disposed on the rotation shaft, the electronic device may operate in one mode among a first mode for rotating the housing, a second mode for adjusting the exposed portion of the flexible display, or a third mode for adjusting the exposed portion of the flexible display and rotating the housing, through adjustment of the position of the rotation shaft. According to various embodiments, the position of the rotation shaft may be automatically or manually adjusted.

According to various embodiments, the processor 1130 may control the driving structure to perform at least one of rotation of the housing or adjustment of the exposed portion of the flexible display based on the executed function if user authentication succeeds. For example, the processor 1130 may control the driving structure to perform at least one of rotation of the housing or adjustment of the exposed portion of the flexible display based on at least one of the size, ratio, or direction of the screen corresponding to the executed function. For example, the function may include at least one of display of the home screen, execution of an application (e.g., video playback, navigation, map, or messaging), or execution of the payment function. The driving structure control operation according to the executed function is described below with reference to FIGS. 36 to 44 .

According to various embodiments, when the position of the rotation shaft is automatically adjusted, if user authentication succeeds, the processor 1130 may identify one of the first mode to the third mode based on the executed function and move the rotation shaft to operate in the identified mode. For example, the processor 1130 may identify one of the first mode to the third mode to change the currently exposed portion of the flexible display and direction to correspond to the executed function. According to various embodiments, the processor 1130 may move the rotation shaft to operate in the identified mode and rotate the housing and/or adjust the exposed portion of the flexible display in the identified mode to be suitable for the executed function.

According to various embodiments, when the position of the rotation shaft is manually adjusted through the crown, the processor 1130 may identify the mode corresponding to the position of the crown detected using the sensor for detecting the position of the crown. For example, the sensor for detecting the position of the crown may be a hall IC that is disposed in the housing and detects the strength of the magnetic field of the magnet disposed in the crown. According to various embodiments, the processor 1130 may identify the position of the crown based on the strength value of the magnetic field sensed by the sensor for detecting the position of the crown and identify the mode corresponding to the identified position of the crown.

According to various embodiments, if user authentication succeeds, the processor 1130 may compare the mode identified based on the position of the crown with the mode corresponding to the executed function. For example, if the mode identified based on the position of the crown differs from the mode corresponding to the executed function, the processor 1130 may display a message to request to adjust the position of the crown to become the mode corresponding to the executed function, on the exposed portion of the flexible display. According to various embodiments, upon detecting the adjustment of the position of the crown to become the mode corresponding to the executed function, the processor 1130 may control the driving structure to rotate the housing and/or adjust the exposed portion of the flexible display in the mode corresponding to the executed function.

In another embodiment, if the mode identified based on the position of the crown is the same as the mode corresponding to the executed function, the processor 1130 may control the driving structure to rotate the housing and/or adjust the exposed portion of the flexible display to be suitable for the executed function without changing the mode. An embodiment for manually changing the mode is described below with reference to FIG. 41 .

According to various embodiments, if the mutual coupling of the plurality of coupling portions is maintained after user authentication succeeds, the processor 1130 may execute a function requiring user authentication without an additional authentication operation. For example, the function requiring user authentication may be execution of a security folder or a payment function. The operation of executing the function requiring user authentication without an additional authentication operation is described below with reference to FIG. 40 .

According to various embodiments, upon receiving information indicating that user authentication fails from the sub processor 1240, the processor 1130 may activate only set functions. For example, the processor 1130 may activate only the clock function when user authentication fails. In another embodiment, when user authentication fails, the processor 1130 may display a message to re-request user authentication a preset number of times and, if user authentication fails a preset number of times or more, activate only preset functions. Operations according to the user authentication result are described below with reference to FIG. 39 .

According to various embodiments, the sub processor 1240 may determine whether to supply the power of the second battery 1270 to the first battery 1140 based on the user authentication result.

For example, if user authentication succeeds, the sub processor 1240 may determine to supply the power of the second battery 1270 to the first battery 1140 and wirelessly transmit power to the first coil 1150 connected with the first battery 1140 through the second coil 1280. According to various embodiments, if power is supplied to the first battery 1140, the processor 1130 may control the driving structure.

In another embodiment, if user authentication fails, the sub processor 1240 may not supply the power of the second battery 1270 to the first battery 1140. Thus, if user authentication fails, the main body does not receive power and may not be driven.

Although FIG. 32 illustrates that power is wirelessly transmitted/received through the first coil 1150 and the second coil 1280, according to various embodiments, power may be wiredly transmitted/received through a pin contact.

According to various embodiments, the processor 1130 or the sub processor 1240 may provide a feedback for the user authentication result. For example, the processor 1130 may display information about success or failure in user authentication on the exposed portion of the flexible display or provide at least one of a sound feedback or vibration feedback. In another embodiment, the sub processor 1240 may provide a feedback for the antenna unit result through an LED included in the mounting member 1200 or provide at least one of a sound feedback or vibration feedback. For example, when a feedback for the user authentication result is provided through the LED, the sub processor 1240 provide the feedback by emitting green light when authentication succeeds, emitting red light when authentication fails, flickering green light when authentication is in progress and flickering red light when reauthentication is required.

According to various embodiments, upon detecting separation of the plurality of coupling portions, the sub processor 1240 may transmit information indicating that the plurality of coupling portions are separated to the processor 1130. According to various embodiments, upon receiving the information indicating that the plurality of coupling portions are separated, the processor 1130 may switch to an unauthenticated state. For example, upon detecting separation of the plurality of coupling portions after user authentication succeeds in a state in which the plurality of coupling portions are coupled together, the processor 1130 may switch to the unauthenticated state to re-request user authentication or activate only set functions. As another embodiment, upon detecting separation of the plurality of coupling portions after user authentication succeeds in a state in which the plurality of coupling portions are coupled together, the sub processor 1240 may switch to the unauthenticated state and may not supply the power of the second battery 1270 to the first battery 1140.

Although FIG. 32 illustrates that the user authentication operation is performed by the sub processor 1240, according to various embodiments, the sub processor 1240 may transmit only the sensing value detected by the sensor 1250 to the processor 1130, and the processor 1130 may perform the user authentication operation.

FIG. 33 is a view illustrating a configuration of an electronic device according to an embodiment of the disclosure. FIG. 33 illustrates an embodiment in which a sub processor is not disposed in the mounting member 1200 (e.g., the strap 1210, sub housing 1220, and the plurality of coupling portions 1230 of FIG. 31 ).

Referring to FIG. 33 , the main body 1100 (e.g., the main body 1100 of FIG. 31 ) may include a processor 1130 (e.g., the processor 120 of FIG. 1 ), a battery 1140 (e.g., the battery 189 of FIG. 1 ), and a first contact pin 1151 for communicating with the mounting member 1200. According to various embodiments, the main body 1100 may further include a communication module (e.g., the communication module 190 of FIG. 1 ) for performing communication with the mounting member 1200 or an external electronic device, a memory (e.g., the memory 130 of FIG. 1 ), a driving structure (e.g., the gear structure 450 of FIG. 8 or the gear structure 550 of FIG. 14 ) configured to adjust the exposed portion of the flexible display (e.g., the display module 160 of FIG. 1 or the flexible display 1120 of FIG. 31 ) and/or rotation of the housing (e.g., the housing 1110 of FIG. 31 ), and a plurality of sensors (e.g., the sensor module 176 of FIG. 1 ) for detecting the operation state of the electronic device or external environment state.

According to various embodiments, the mounting member 1200 may include a magnet 1233 disposed in at least one of the plurality of coupling portions (e.g., the plurality of coupling portions 1230 of FIG. 31 ), a coupling detection sensor 1234 (e.g., hall IC) for detecting coupling or separation of the plurality of coupling portions, a sensor 1250 for user authentication (e.g., fingerprint recognition sensor or blood vessel recognition sensor), and a second contact pin 1181 for communicating with the main body 1100.

According to various embodiments, the mounting member 1200 may further include a communication module (e.g., the communication module 190 of FIG. 1 ) for performing communication with an external electronic device, a memory (e.g., the memory 130 of FIG. 1 ) and a plurality of sensors (e.g., the sensor module 176 of FIG. 1 ) for detecting the operation state of the electronic device or external environment state.

According to various embodiments, the processor 1130 may receive a sensing value from at least one of the coupling detection sensor 1234 or the sensor 1250 for user authentication through the first contact pin 1141 and the second contact pin 1181.

For example, upon detecting the mutual coupling of the plurality of coupling portions through the coupling detection sensor 1234, the processor 1130 may perform user authentication based on the sensing value detected through the sensor 1250 for user authentication.

According to various embodiments, the processor 1130 may perform the operation of detecting coupling of the plurality of coupling portions and user authentication operation using the sensing value detected through the sensor 1250 by the sub processor 1240, as well as the operation by the processor 1130 shown in FIG. 32 .

FIGS. 34A, 34B, and 34C are views illustrating a user authentication method of an electronic device according to various embodiments of the disclosure. For example, FIGS. 34A and 34B illustrate an embodiment of performing user authentication through fingerprint recognition, and FIG. 34C illustrates an embodiment of performing user authentication through blood vessel recognition.

According to various embodiments, the sensors 1251 and 1252 for user authentication (e.g., the sensor module 176 of FIG. 1 , the sensor 1250 of FIG. 32 , or the sensor 1250 of FIG. 33 ) may be fingerprint recognition sensors disposed in at least a partial area of the plurality of coupling portions (e.g., the plurality of coupling portions 1230 of FIG. 31 , the first coupling portion 1231, or the second coupling portion 1232).

Referring to FIG. 34A, the sensor 1251 may be disposed on the surface opposite to the surface contacting the human body among the plurality of coupling portions.

Referring to FIG. 34B, the sensor 1252 may be disposed on a side surface of the plurality of coupling portions. Thus, when the user's finger contacts the plurality of coupling portions for mutual coupling of the plurality of coupling portions, the sensors 1251 and 1252 may detect the user's fingerprint.

According to various embodiments, the sensor 1253 for user authentication may be a blood vessel recognition sensor (e.g., an infrared sensor for detecting arteries and/or veins) disposed in at least a portion of the mounting member (e.g., the mounting member 1200 of FIG. 31 ).

Referring to FIG. 34C, the sensor 1253 may be disposed on at least a portion of the surface contacting the human body of the mounting member and detect the user's blood vessel.

According to various embodiments, the sensor for user authentication is not limited to the fingerprint recognition sensor or blood vessel recognition sensor shown in FIG. 32 but may be included in the main body (e.g., the main body 1100 of FIG. 31 ). For example, the sensor for user authentication may include a fingerprint recognition sensor included in the flexible display (e.g., the flexible display 1120 of FIG. 31 ) or housing (e.g., the housing 1110 of FIG. 31 ) of the main body and may include an iris recognition sensor included in the main body.

FIG. 35 is a view illustrating an operation of adjusting an exposed portion of a flexible display and rotation of a housing of an electronic device according to an embodiment of the disclosure.

Referring to FIG. 35 , a state in which a dot is positioned at an upper left end of the flexible display (e.g., the display module 160 of FIG. 1 or the flexible display 1120 of FIG. 31 ) may be assumed to be a normal state 1101 of the electronic device (e.g., the electronic device 101 of FIG. 1 or the electronic device 1000 of FIG. 31 ). The dot positioned at the upper left end of the flexible display is illustrated to describe the state of the electronic device, and is not displayed on the flexible display.

For example, at least one of the rotation of the housing of the electronic device or the adjustment of the exposed portion of the flexible display may be performed by the rotation of the rotation shaft (e.g., the rotation shaft 550 a of FIG. 18 or the rotation shaft 550 a of FIG. 23 ) disposed in the housing.

According to various embodiments, if the exposed portion of the flexible display is extended in the normal state 1101 of the electronic device, the electronic device may be changed into the extended state 1102. For example, if the exposed portion of the flexible display is extended to the left in the normal state 1101, the dot at the upper left end of the flexible display may also be in the extended state 1102 which it has been moved to the left according to the extension of the flexible display. According to various embodiments, if the exposed portion of the flexible display is shrunken in the extended state 1102 of the electronic device, the electronic device may be changed into the normal state 1101.

According to various embodiments, if the housing is rotated in the normal state 1101, the electronic device may be changed into the rotated state 1103. For example, if the housing is rotated clockwise in the normal state 1101, the dot at the upper left end of the flexible display may be in the rotated state 1103 in which it has been moved to the upper right end. According to various embodiments, if the housing is rotated counterclockwise in the rotated state 1103 of the electronic device, the electronic device may be changed into the normal state 1101.

According to various embodiments, if the exposed portion of the flexible display is extended in the rotated state 1103, the electronic device may be changed into the extended and rotated state 1104. For example, if the exposed portion of the flexible display is extended upward in the rotated state 1102, the dot at the upper right end of the flexible display may also be in the extended and rotated state 1104 in which it has been moved upward according to the extension of the flexible display. According to various embodiments, if the exposed portion of the flexible display is shrunken in the extended and rotated state 1104, the electronic device may be changed into the rotated state 1102.

According to various embodiments, if the housing is rotated in the extended state 1102 of the electronic device, the electronic device may be changed into the extended and rotated state 1104. For example, if the housing is rotated clockwise in the extended state 1102 of the electronic device, the dot at the upper left end of the flexible display may be in the extended and rotated state 1104 in which it has been moved to the upper right end. According to various embodiments, if the housing is rotated counterclockwise in the extended and rotated state 1104 of the electronic device, the electronic device may be changed into the extended state 1102.

The rotation direction of the housing may be varied depending on the rotation direction or arrangement structure of the rotation shaft and, according to various embodiments, the housing of the electronic device may be rotated counterclockwise in the normal state 1101 and, in the rotated state 1103, be rotated clockwise.

The direction of adjustment of the exposed portion of the flexible display has been described as extension to the left in the normal state 1101. However, according to various embodiments, the extension may be performed right, upward, downward, or in two opposite directions in the normal state 1101.

Although FIG. 35 illustrates an embodiment in which rotation of the housing or adjustment of the exposed portion of the flexible display is independently performed, as shown in FIG. 36 , rotation of the housing and adjustment of the exposed portion of the flexible display may be performed in association with each other.

FIG. 36 is a view illustrating an operation of adjusting an exposed portion of a flexible display and rotation of a housing of an electronic device according to an embodiment of the disclosure.

Referring to FIG. 36 , a state in which a dot is positioned at an upper left end of the flexible display (e.g., the display module 160 of FIG. 1 or the flexible display 1120 of FIG. 31 ) may be assumed to be a normal state 1101 of the electronic device (e.g., the electronic device 101 of FIG. 1 or the electronic device 1000 of FIG. 31 ). The dot positioned at the upper left end of the flexible display is illustrated to describe the state of the electronic device, and is not displayed on the flexible display.

For example, when the electronic device includes the structure of FIG. 8 or 28 , adjustment of the housing and adjustment of the exposed portion of the flexible display may be performed together by rotation of the rotation shaft (e.g., the rotation shaft 450 a of FIG. 8 or the rotation shaft 550 a of FIG. 28 ).

According to various embodiments, according to rotation of the rotation shaft in one direction in the normal state 1101, the electronic device may be changed into the extended and rotated state 1105 in which the exposed portion of the flexible display is adjusted while the housing is rotated. For example, according to rotation of the rotation shaft in the normal state 1101, the electronic device may be changed into the extended and rotated state 1105 in which the housing is rotated counterclockwise while the exposed portion of the flexible display is extended. For example, in the normal state 1101, the dot positioned at the upper left end of the flexible display may be moved to the lower left end of the flexible display according to rotation of the housing and be moved to the left according to extension of the exposed portion of the flexible display.

According to various embodiments, in the extended and rotated state 1105, according to rotation of the rotation shaft in the opposite direction, the electronic device may be changed into the normal state 1101 in which the housing is rotated clockwise while the exposed portion of the flexible display is shrunken.

Although FIG. 36 illustrates that the exposed portion of the flexible display is extended as the housing is rotated counterclockwise, and the exposed portion of the flexible display is shrunken as the housing is rotated clockwise, according to various embodiments, extension or shrinkage of the exposed portion and the rotation direction may be varied depending on the arrangement structure of the plurality of gear portions for controlling the exposed portion of the flexible display and the plurality of gear portions for rotating the housing on the rotation shaft.

FIG. 37 is a view illustrating an operation mode of adjusting an exposed portion of a flexible display and rotation of a housing of an electronic device according to an embodiment of the disclosure.

For example, when the electronic device includes a rotation shaft (e.g., the rotation shaft 550 a of FIG. 14 ) where a plurality of gear portions are disposed for rotation, the electronic device may automatically or manually move the rotation shaft (e.g., the rotation shaft 550 a of FIG. 14 ) to change the operation mode. For example, the operation mode may include a first mode (mode 1) for rotating the housing 1110, a second mode (mode 2) for adjusting the exposed portion of the flexible display, or a third mode (mode 3) for adjusting the exposed portion of the flexible display and rotating the housing.

Referring to FIG. 37 , the electronic device may include the rotation shaft 1160 in the housing 1110 and may include a crown 1161 connected with one side end of the rotation shaft 1160 and disposed outside the housing 1110. According to various embodiments, the rotation shaft 1160 may include three grooves 1162 (e.g., the plurality of stopper members 501 of FIG. 17 ) respectively corresponding to the first mode, the second mode, and the third mode. For example, the three grooves 1162 may be a groove corresponding to the third mode, a groove corresponding to the second mode, or a groove corresponding to the first mode in the order from the crown 1161. According to various embodiments, the order of the grooves may be varied depending on the arrangement structure of the plurality of gear portions disposed on the rotation shaft.

According to various embodiments, the electronic device may identify the mode based on the position of the crown moved by the user's manual manipulation. As another embodiment, the electronic device may automatically move the rotation shaft 1160 using the motor provided in the housing 1110, determining the operation mode. According to various embodiments, when automatically moving the rotation shaft, the electronic device may omit the crown 1161.

According to various embodiments, a state in which a dot is positioned at an upper left end of the flexible display (e.g., the display module 160 of FIG. 1 or the flexible display 1120 of FIG. 31 ) may be assumed to be a normal state 1101 of the electronic device (e.g., the electronic device 101 of FIG. 1 or the electronic device 1000 of FIG. 31 ). The dot positioned at the upper left end of the flexible display is illustrated to describe the state of the electronic device, and is not displayed on the flexible display.

According to various embodiments, when a stopper protrusion (e.g., the stopper protrusion 502 of FIG. 17 ) is fixed to the groove corresponding to the first mode for rotating the housing, among the three grooves 1162, in the normal state 1101 so that the electronic device operates in the first mode, the housing may be rotated by rotation of the rotation shaft 1160, changing the electronic device into the rotated state 1106. For example, the electronic device may be rotated counterclockwise according to rotation of the rotation shaft 1160 in one direction in the normal state 1101 and be changed into the rotated state 1106 in which the dot is positioned at the lower left end of the flexible display. According to various embodiments, the electronic device may be rotated clockwise according to rotation of the rotation shaft 1160 in the opposite direction in the rotated state 1106 and be changed into the normal state 1101.

According to various embodiments, when the stopper protrusion is fixed to the groove corresponding to the second mode for adjusting the exposed portion of the flexible display, among the three grooves 1162, in the normal state 1101 so that the electronic device operates in the second mode, the exposed portion of the flexible display may be extended by rotation of the rotation shaft 1160, changing the electronic device into the extended state 1107. For example, the flexible display may be extended upward according to rotation of the rotation shaft 1160 in one direction in the normal state 1101, so that the electronic device may be changed into the extended state 1107 in which the dot at the upper left end of the flexible display has been moved upward. According to various embodiments, the extended portion of the flexible display may be shrunken downward according to rotation of the rotation shaft 1160 in the opposite direction in the extended state 1107, so that the electronic device may be changed into the normal state 1101.

According to various embodiments, when the stopper protrusion is fixed to the groove corresponding to the third mode for adjusting the exposed portion of the flexible display and rotating the housing, among the three grooves 1162, in the normal state 1101 so that the electronic device operates in the third mode, the exposed portion of the flexible display may be extended and the housing may be rotated by rotation of the rotation shaft 1160, changing the electronic device into the extended and rotated state 1105. For example, according to rotation of the rotation shaft 1160 in one direction in the normal state 1101, the housing may be rotated counterclockwise, and the upper edge portion of the flexible display in the normal state 1101 may be extended to the left along with rotation of the housing, so that the electronic device may be changed into the extended and rotated state 1105 in which the dot at the upper left end of the flexible display has been moved downward and further left. According to various embodiments, according to rotation of the rotation shaft 1160 in the opposite direction in the extended and rotated state 1105, the housing may be rotated clockwise while the extended portion of the flexible display may be shrunken, changing the electronic device into the normal state 1101.

According to various embodiments, extension or shrinkage of the exposed portion and the rotation direction may be varied depending on the arrangement structure of the plurality of gear portions for controlling the exposed portion of the flexible display and the plurality of gear portions for rotating the housing on the rotation shaft.

FIG. 38 is a view illustrating an operation of controlling an exposed portion of a flexible display and rotation of a housing of an electronic device according to an embodiment of the disclosure.

According to various embodiments, in operation 1310, upon detecting mutual coupling of the plurality of coupling portions (e.g., the plurality of coupling portions 1230 of FIG. 31 ), the electronic device (e.g., the electronic device 101 of FIG. 1 , the processor 1130 of FIG. 32 , the sub processor 1240 of FIG. 32 , or the processor 1130 of FIG. 33 ) may perform user authentication based on the sensing value detected by the sensor (e.g., the sensor 1250 of FIG. 32 or the sensor 1250 of FIG. 33 ).

According to various embodiments, if the user authentication operation is performed by the sub processor, the sub processor may transmit the user authentication result to the processor.

According to various embodiments, in operation 1320, the electronic device may control the driving structure (e.g., the gear structure 450 of FIG. 8 or the gear structure 550 of FIG. 14 ) configured to adjust the exposed portion of the flexible display (e.g., the flexible display 1120 of FIG. 31 ) and/or rotate the housing (e.g., the housing 1110 of FIG. 31 ) based on the user authentication result.

For example, the electronic device may control the driving structure to perform at least one of rotation of the housing or adjustment of the exposed portion of the flexible display based on the executed function if user authentication succeeds.

According to various embodiments, the electronic device may control the driving structure to perform, in realtime, at least one of rotation of the housing or adjustment of the exposed portion of the flexible display further considering at least one of the position of the electronic device or direction of the electronic device detected using the sensor (e.g., speed sensor, accelerometer, rotation angle sensor, angular speed sensor, or position sensor) included in the electronic device. For example, when the executed function is a navigation application, the electronic device may rotate the housing or adjust the exposed portion of the flexible display further considering at least one of the position or direction of the electronic device, or the navigation screen displayed on the flexible display. For example, the electronic device may rotate the housing by 90 degrees counterclockwise when a left turn is required, extend the exposed portion of the flexible display when the distance to go straight is long, and gradually shrink the exposed portion of the flexible display as the distance reduces. Accordingly, the electronic device may more intuitively provide content to the user.

According to various embodiments, the driving structure may include at least one of a rotation shaft (e.g., the rotation shaft 450 a of FIG. 8 or the rotation shaft 550 a of FIG. 14 ), a crown (e.g., the rotation knob 454 of FIG. 5 or the rotation knob 555 of FIG. 14 ) connected with a side end of the rotation shaft to manually move the rotation shaft, a sensor (e.g., the sensor module 176 of FIG. 1 ) for detecting the position of the crown, or a driving motor (e.g., the driving motor 480 of FIG. 5 or the driving motor 580 of FIG. 14 ) connected with the other side end of the rotation shaft to rotate the rotation shaft about the rotation shaft. According to various embodiments, the electronic device may omit the crown and, if included, the crown may be disposed outside the housing.

For example, a plurality of first gear portions related to adjustment of the exposed portion of the flexible display and at least one second gear portion related to rotation of the housing may be disposed on the rotation shaft.

According to various embodiments, as shown in FIG. 8 , when the plurality of first gear portions (e.g., the second gear portion 452 of FIG. 8 ) and one second gear portion (e.g., the first gear portion 451 of FIG. 8 ) are disposed on the rotation shaft, if user authentication succeeds, the electronic device may control the driving structure based on the executed function to adjust the exposed portion of the flexible display while rotating the housing.

According to various embodiments, as shown in FIG. 14 , when the plurality of first gear portions and the plurality of second gear portions are disposed on the rotation shaft, the electronic device may operate in one mode among a first mode for rotating the housing, a second mode for adjusting the exposed portion of the flexible display, or a third mode for adjusting the exposed portion of the flexible display and rotating the housing, through adjustment of the position of the rotation shaft.

For example, if user authentication succeeds, the electronic device may determine whether only housing rotation is needed, only adjustment of the exposed portion of the flexible display is needed, or rotation of the housing and adjustment of the exposed portion of the flexible display are needed based on the executed function and control the driving structure to operate in one mode among the first mode to the third mode.

According to various embodiments, if the position of the rotation shaft may be manually adjusted, the electronic device may display a message requesting to adjust the position of the crown to correspond to the determine mode on the exposed portion of the flexible display. According to various embodiments, upon detecting the position of the crown as being the position corresponding to the determined mode, the electronic device may control the driving structure according to the determined mode.

According to various embodiments, the electronic device may identify the direction of the housing and the exposed portion of the flexible display according to the control of the driving structure and identify at least one content and layout to be displayed on the flexible display based on the identified direction of the housing and exposed portion of the flexible display. For example, when the rotation of the housing or adjustment of the exposed portion of the flexible display is automatically performed through control of the driving structure or the rotation of the housing or adjustment of the exposed portion of the flexible display is performed by the user's manual manipulation, the electronic device may identify the direction of the housing and the exposed portion of the flexible display and identify at least one content and layout to be displayed on the flexible display based on the identified direction of the housing and the exposed portion of the flexible display.

According to various embodiments, the electronic device may display the identified at least one content in the identified layout, on the exposed portion of the flexible display. Various embodiments related to the layout of content based on the direction of the housing and the exposed portion of the flexible display are described below with reference to FIGS. 48A to 48D, 49A to 49C, 50A to 50D, and 51A to 51C.

FIG. 39 is a view illustrating an operation of controlling an exposed portion of a flexible display and rotation of a housing of an electronic device according to a user authentication result according to an embodiment of the disclosure.

According to various embodiments, in operation 1410, the electronic device (e.g., the electronic device 101 of FIG. 1 , the processor 1130 of FIG. 32 , the sub processor 1240 of FIG. 32 , or the processor 1130 of FIG. 33 ) may detect mutual coupling of the plurality of coupling portions (e.g., the plurality of coupling portions 1230 of FIG. 31 ). For example, the electronic device may detect mutual coupling of the plurality of coupling portions based on detection of approach of the magnet provided in at least one of the plurality of coupling portions through a hall IC provided in one of the plurality of coupling portions.

According to various embodiments, in operation 1420, the electronic device may perform a user authentication operation. For example, the electronic device may perform user authentication based on at least one of the fingerprint recognition sensor disposed in at least a portion of the plurality of coupling portions, a blood vessel recognition sensor disposed in the mounting member (e.g., the mounting member 1200 of FIG. 31 ), or the fingerprint recognition sensor or iris recognition sensor disposed in the main body (e.g., the main body 1100 of FIG. 31 ).

According to various embodiments, if user authentication fails (no in operation 1420, the electronic device may activate only set functions in operation 1430. For example, if user authentication fails, the electronic device may activate only the clock function. As another embodiment, if user authentication fails, the electronic device may not supply the power of the second battery (e.g., the second battery 1270 of FIG. 32 ) disposed in the mounting member to the first battery (e.g., the first battery 1140 of FIG. 32 ).

According to various embodiments, if user authentication fails, the electronic device may repeat the user authentication operation a set number of times and, if user authentication fails despite the repeated user authentication operation, activate only set functions.

According to various embodiments, if user authentication succeeds (yes in operation 1420), the electronic device may transmit the authentication result in operation 1440. For example, when the user authentication operation is performed by the sub processor, the sub processor may transmit the user authentication result to the processor. As another embodiment, when the user authentication operation is performed by the processor, operation 1440 may be omitted.

According to various embodiments, in operation 1450, the electronic device may detect separation of the plurality of coupling portions. For example, upon detecting separation of the plurality of coupling portions after user authentication succeeds (yes in operation 1450), the electronic device may return to operation 1420 to perform user authentication again. For example, upon detecting separation of the plurality of coupling portions after user authentication succeeds, the electronic device may switch to the unauthenticated state and perform user authentication again.

According to various embodiments, if separation of the plurality of coupling portions is not detected after user authentication succeeds (no in operation 1450), the electronic device may maintain the state in which user authentication succeeds. For example, the electronic device may perform the operation of controlling the driving structure or perform functions requiring user authentication without additional authentication until separation of the plurality of coupling portions is detected after user authentication succeeds.

FIG. 40 is a view illustrating an operation of adjusting an exposed portion of a flexible display and rotation of a housing of an electronic device according to an embodiment of the disclosure.

Referring to FIG. 40 , if the plurality of coupling portions are coupled to each other, the electronic device may perform the authentication operation in operation 1510. For example, operation 1510 may be the same as operation 1420 of FIG. 39 .

According to various embodiments, if user authentication fails (no in operation 1510), the electronic device may perform user authentication again. According to various embodiments, if user authentication fails a set number of times, the electronic device may activate set functions (e.g., clock function) and stop supplying power to the main body (e.g., the main body 1100 of FIG. 31 ).

According to various embodiments, if user authentication succeeds (yes in operation 1510), the electronic device may receive a request for executing a function requiring authentication in operation 1520. For example, in a state in which user authentication succeeds, the electronic device may receive a request for executing a function requiring user authentication.

According to various embodiments, in operation 1530, the electronic device may detect mutual coupling of the plurality of coupling portions. For example, the electronic device may detect mutual coupling of the plurality of coupling portions based on detection of approach of the magnet provided in at least one of the plurality of coupling portions through a hall IC provided in one of the plurality of coupling portions.

According to various embodiments, if the plurality of coupling portions are not coupled to each other (no in operation 1530), the electronic device may activate only set functions in operation 1540. For example, the electronic device may activate only the clock function.

According to various embodiments, in a state in which only the clock function has been activated, the electronic device may return to operation 1510 to perform the user authentication operation again.

According to various embodiments, if the plurality of coupling portions are coupled to each other (yes in operation 1530), the electronic device may identify whether the coupling count at the time of user authentication is identical to the current count in operation 1550. For example, the coupling count may be information related to how many times the plurality of coupling portions have been coupled to each other and, whenever the plurality of coupling portions are coupled to each other, the coupling count may increment.

For example, the electronic device may compare the coupling count at the time of success in authentication according to operation 1510 with the current coupling count and, if different (no in operation 1550), identify that the user authentication for the current coupling count is in the unauthenticated state. According to various embodiments, if the coupling counts differ from each other, the electronic device may activate only set functions in operation 1540.

According to various embodiments, the electronic device may compare the coupling count at the time of success in authentication according to operation 1510 with the current coupling count and, if the same (yes in operation 1550), identify that the user authentication for the current coupling count is in the state in which user authentication succeeds. According to various embodiments, in operation 1560, the electronic device may execute the requested function. For example, if the coupling counts are the same, the electronic device may request to execute a function requiring authentication without additional authentication.

FIG. 41 is a view illustrating an operation of controlling an exposed portion of a flexible display and rotation of a housing of an electronic device according to a function according to an embodiment of the disclosure. FIG. 41 may illustrate, e.g., operations after the plurality of coupling portions (e.g., the plurality of coupling portions 1230 of FIG. 31 ) are coupled to each other and the user authentication operation succeeds.

According to various embodiments, in operation 1610, the electronic device (e.g., the electronic device 101 of FIG. 1 , the processor 1130 of FIG. 32 , or the processor 1130 of FIG. 33 ) may identify the current exposed portion and current direction of the flexible display (e.g., the display module 160 of FIG. 1 or the flexible display 1120 of FIG. 31 ). For example, the current direction of the flexible display may be the direction of the housing (e.g., the housing 1110 of FIG. 31 ).

According to various embodiments, in operation 1630, the electronic device may identify the exposed portion and direction of the flexible display for each function. For example, the electronic device may identify the direction of the housing and the exposed portion of the flexible display based on at least one of the size, ratio, or direction of the screen appropriate for the function requested to be executed.

According to various embodiments, in operation 1640, the electronic device may determine whether they are the same as the current exposed portion and direction of the flexible display.

For example, if the current exposed portion and direction of the flexible display are the same as the exposed portion and direction of the flexible display corresponding to the function requested to be executed (yes in operation 1640), the electronic device may execute the requested function in operation 1650.

According to various embodiments, if the current exposed portion and direction of the flexible display differs from the exposed portion and direction of the flexible display corresponding to the function requested to be executed (no in operation 1640), the electronic device may display a crown position change message in operation 1660. For example, the electronic device may identify one mode among a first mode for rotating the housing to change the current exposed portion and direction of the flexible display to correspond to the exposed portion and direction of the flexible display corresponding to the function requested to be executed, a second mode for adjusting the exposed portion of the flexible display, or a third mode for adjusting the exposed portion of the flexible display and rotating the housing.

According to various embodiments, when the current position of the crown differs from the position of the crown corresponding to the identified mode, the electronic device may display a crown position change message on the exposed portion of the flexible display to change the position of the crown to the position corresponding to the identified mode.

According to various embodiments, when the electronic device includes the structure of FIG. 8 or when the electronic device includes a rotation shaft (e.g., the rotation shaft 550 a of FIG. 14 ) where a plurality of gear portions for rotation are disposed and a mode change may be automatically performed, operation 1660 may be omitted.

According to various embodiments, upon detecting the position of the crown as the position corresponding to the identified mode, the electronic device may adjust the exposed portion of the flexible display and/or rotate the housing in operation 1670. For example, the electronic device may adjust the exposed portion of the flexible display and/or rotate the housing by rotating the rotation shaft (e.g., the rotation shaft 450 a of FIG. 8 or the rotation shaft 550 a of FIG. 14 ) of the driving structure (e.g., the gear structure 450 of FIG. 8 or the gear structure 550 of FIG. 14 ).

According to various embodiments, when operation 1660 is omitted, if the current exposed portion and direction of the flexible display differs from the exposed portion and direction of the flexible display corresponding to the function requested to be executed (no in operation 1640), the electronic device may rotate the housing and/or adjust the exposed portion of the flexible display.

According to various embodiments, if the housing is rotated and/or the exposed portion of the flexible display is adjusted, the electronic device may execute the requested function in operation 1650.

FIG. 42 is a view illustrating an operation of rotating a screen according to a rotation operation of a housing of an electronic device according to an embodiment of the disclosure. FIG. 42 may illustrate, e.g., operations after the plurality of coupling portions (e.g., the plurality of coupling portions 1230 of FIG. 31 ) are coupled to each other and the user authentication operation succeeds.

According to various embodiments, in operation 1710, the electronic device (e.g., the electronic device 101 of FIG. 1 , the processor 1130 of FIG. 32 , or the processor 1130 of FIG. 33 ) may rotate the flexible display (e.g., the display module 160 of FIG. 1 or the flexible display 1120 of FIG. 31 ). For example, the electronic device may rotate the flexible display by rotating the housing (e.g., the housing 1110 of FIG. 31 ).

According to various embodiments, in operation 1720, the electronic device may determine whether a rotation value of the flexible display is met. For example, the electronic device may determine whether the rotation value of the flexible display is a threshold or more with respect to the mounting member (e.g., the mounting member 1200 of FIG. 31 or the strap 1210 of FIG. 31 ). According to various embodiments, the electronic device may obtain the rotation value of the flexible display using at least one sensor (e.g., rotation angle sensor or angular speed sensor) included in the main body (e.g., the main body 1100 of FIG. 31 ).

FIG. 43 is a view illustrating an operation of rotating a screen according to a rotation operation of a housing of an electronic device according to an embodiment of the disclosure.

According to various embodiments, if the rotation value of the flexible display is not met (no in operation 1720), the electronic device may maintain the current screen in operation 1730. For example, when the flexible display is in a horizontal direction 1800 as shown in FIG. 43 , the electronic device may display content 1810 in a layout based on the horizontal direction on the flexible display. According to various embodiments, when the flexible display is rotated until before reaching the threshold with respect to the mounting member (e.g., the mounting member 1200 of FIG. 31 or the strap 1210 of FIG. 31 ), the electronic device may maintain the content 1810 in the layout based on the horizontal direction.

According to various embodiments, if the rotation value of the flexible display is met (yes in operation 1720), the electronic device may determine whether a moving direction guide is running. For example, the electronic device may determine whether the moving direction guide according to execution of the navigation function is running.

For example, when the navigation function is running, the flexible display may be rotated in real time based on the moving direction guided, as shown in FIG. 47 . In this case, if the layout of the screen is changed, the user may get confused. Thus, if the moving direction guide is running (yes in operation 1740), the electronic device may maintain the current screen in operation 1750.

According to various embodiments, unless the moving direction guide is running (no in operation 1740), the electronic device may switch the direction of the screen in operation 1760. For example, when the flexible display is in a horizontal direction 1800 as shown in FIG. 43 , the electronic device may display content 1810 in a layout based on the horizontal direction on the flexible display. According to various embodiments, when the flexible display is rotated by the threshold or more with respect to the mounting member to be positioned in the vertical direction 1820, the electronic device may change the content 1810 in the layout based on the horizontal direction into content 1830 based on in a layout based on the vertical direction and display it.

Referring to FIG. 43 , when the content 1810 in the layout based on the horizontal direction is changed into the content 1830 in the layout based on the vertical direction, the electronic device may also display contents 1821, 1822, and 1823 that gradually rotate from the horizontal direction to the vertical direction.
